| description | We report the first successful application of an N-TiO2–Ag nanocomposite as an efficient photoanode for highly efficient dye-sensitized solar cells (DSSC). The N-TiO2–Ag nanocomposites with different Ag contents were prepared using a simple chemical reduction method and characterized using various suitable techniques. The DSSC assembled with the N-TiO2–Ag-modified photoanode demonstrated an enhanced solar-to-electrical energy conversion efficiency of 8.15% compared to the photoanode of a DSSC composed of unmodified TiO2 (2.19%) under full sunlight illumination (100 mW cm−2, AM 1.5 G). This superior DSSC performance was due to the reduced band gap energy and retarded charge recombination that resulted from the introduction of plasmonic Ag nanoparticles on the surface of N-TiO2. The influence of the Ag content on the overall efficiency was also investigated, and the optimum Ag content for N-TiO2 was found to be 10 wt%. The enhanced solar energy conversion efficiency demonstrated by the N-TiO2–Ag nanocomposite makes it a promising alternative to conventional photoanode-based DSSCs. |
